Should I get a SH-4 Humbucker for my 96 Mexican strat, or replace the stock speaker in my Peavey VK-112 amp? Idk what speaker I should get, I like hard rock (Smashing Pumpkins, Foo Fighters etc.) My budget is $70 if you think I should get a new speaker. Thanks. Edit: Pickup would go in bridge position.

It's like taking the 4 banger 80 horsepower crap engine out of a smartcar and putting a 500 horse V-8 in there.

A new pickup wont do anything for you unless you have clarity to even hear it. I've owned my Valveking 112 for 6 years I think, this is the biggest mod you can do to it short of replacing the choke and transformer as far as I know.
